NIfTI-1 is a data format proposed by the NifTI (Neuroimaging Informatics Technology Initiative) DFWG (Data Format Working Group) that can be used for storing neuroimaging datasets (e.g. MRI, functional MRI, etc.). This format is adapted from the widely used ANALYZE 7.5 format from Mayo Clinic. A Nifti file consists of a header part containing the meta-data and the raw image data itself. The header and the image data can be stored together in the same file with an *.nii extension or can be split into two files with an *.hdr extension for the header and an *.img extension for the image data.

Re-posting this article on real-time functional MRI I wrote several years ago.

The technique known as functional magnetic resonance imaging (fMRI) has been extensively used to elucidate the functions of the human brain. Functional MRI provides a “window” where we can see what part of the brain is involved when we think, smell, taste, feel, or move. These windows are the activation maps indicating sites in the subject’s brain that are activated while the subject performs a given task and are usually obtained after analyzing voluminous amount of functional MRI images.
